Machinery mounting base

ABSTRACT

The base comprises a base plate having a plurality of slots formed therein, for receiving mounting bolts for machinery frames for mounting the machinery to the base plate, in which some of the slots have a greater width then the diameters of the shanks of the bolts used therewith. Accordingly, the wider slots restrain the bolts at only one side thereof against lateral movement. In addition, a strap coupled to an adjustment bolt is disposed below the slots being used, so that the machinery mounted thereabove can be displaced lengthwise along the base plate. The strap has threaded holes for engaging the machinery mounting bolts.

Base plates in the prior art are already known to have a plurality ofslots so that differently-dimensioned machinery, having differentlypatterned mounting feet and variously-spaced fastening hardware can beused alternately on the same base plate. In this prior art it isarranged that these slots are formed in parallel, so that widermachinery frames can be fastened onto the same base plate which willalso accommodate narrower machinery frames. The difficulty with thisprior art arrangement arises from the fact that, in many circumstances,it is impossible to provision a sufficient number of parallel slots toaccommodate many differentlydimensioned and similarly dimensionedmachinery frames. That is, many machineryframes have mounting areadimensions with such small gradations therebetween, one from another,that there is not sufficient spacing to. provide metal between whatwould otherwise be adjacent, frame-accommodating slots.

To overcome this difficulty in the prior art, it has been the practiceto affix separate fastening slide rails between the machinery and thebase. plate. So also, obviously, it is a common practice to provide aseparate base plate for each, differently-dimensioned item of machinery.Patently, these prior practices are expensive.

It is an object of this invention to set forth an improved base platewhich avoids the prior art difficulties.

It is an object of this invention in particular to provide base meansfor fastener-mounting of machinery thereto, comprising a base plate;said base plate having means for receiving machinery-mounting fasteners,and wherein said fastener-receiving means includes at least a firstplurality of means for restraining only one side of themachinery-mounting fasteners against lateral movement.

A feature of this invention comprises the provisioning of a base platehaving a plurality of slots formed therein for receiving mounting boltsfor machinery frames for mounting the'machinery to the base plate, inwhich some of the slots have a greater width than the diameters of theshanks of the bolts used therewith. Accordingly, the wider slotsrestrain the bolts at only one side thereof against lateral movement. Inaddition, a strap coupled to an adjustment bolt is disposed below theslots being used, so that the machinery mounted thereabove can bedisplaced lengthwise along the base plate. The strap has threaded holesfor engaging the machinery mounting bolts. I

Further objects and features of this invention will become more apparentby reference to the following description taken in conjunction with theaccompanying figures in which:

FIG. 1 is a plan view of the inventive base means, according to theinvention; and

FIG. 2 is a side elevational view, partially in crosssection, of thebase means of FIG. 1.

As shown in FIGS. 1 and 2, the base means comprises a base plate 12having pluralities of slots 14 and 16 which lie parallel with the platelongitudinal axis.

2 Slots 14 have a width which is complementary to the diameter of theshanks of fasteners normally to be used for the mounting of machinery.Slots 16, on the contrary, are wider, having a width in excess of thatrequired for the diameter of the shank of fasteners used to mountmachinery to the base plate. Such fasteners, as bolts 18 in penetrationof a machine mounting frame (only a portion being shown), in FIG. 2, arereceived in a pair of slots 16. i

In FIG. 1 are set out several patterns of bolt shank diameters. Forinstance, there are shown four shank di-' ameter representations 22,illustrative of one pattern. Two of these diameters22 are shown disposedagainst the outer side of slots 16 on one side of the base plate 12, andthe two other bore diameters 22 are shown disposed against the outerside of the other slots 16. Accordingly, machinery mounted to the baseplate 12, with the bores in penetration of the'slots 16 is restrainedagainst lateral movement, even though the slots are excessively wide. v

The shank diameter representations 24 through 28 illustrate the use ofother patterns for mounting other machinery to the same base plate usingthe slots provided. In some of these, specifically diameters 26, it canbe seen that the narrower slots 14 can be used in conjunction with thewider slots 16 for mounting machinery having a mounting frame dimensionand bolt centers distances'which warrant fasteners set out in such aparticular pattern. I I

The patterns represented by shank diameters 22 through 28 warrant theuse of 4 slots, two toward one end of the base plate 12, and twoinboard" thereof, because of the reach of mounting fasteners for certaintypes of machinery anticipated for mounting to plate 12. However, ifother machinery is to be mounted, and the hold-down bolt centersdistance does not require the use of four slots, a pair of juxtaposedslots works equally well, as illustrated by the patterns set out forshank diameters 30 and 32. r

The base plate 12 comprises a pair of side walls 34 which suqport a deck36. Beneath the deck 36 is a strap 38 which has a plurality ofspaced-apart threaded holes 40 formed therein for receiving threadedshank portions of bolts 18. Strap 38 has a perpendicularly extending tab42 which also has a threaded bore 44 for threadedly receiving anadjustment bolt 46. Bolt 46 has a drive head 48 which is restrained by aclip 50 supported on one end of the deck 36.

It is proposed that a pair of straps 38 and the associated bolt 46 andclip 50 can be used underneath the base plate l2for two purposes: forone, of the straps 38 receive and secure the mounting bolts, and servethe purpose of locking nuts. Additionally, if the machine mounted to thebase plate 12 comprises a motor, or the like, having a pulley, orwhatever, for receiving a drive belt (for driving or receiving drivefrom, associated machinery), bolt 46 and strap 38 provide means for adjusting the position of the machinery in order that the drive belt mightbe tensioned and slackened as -warranted.

While I have described my invention in connection with a specificembodiment thereof, it is to be clearly understood that this is doneonly by way of example and not as a limitation to the scope of myinvention as set forth in the objects thereof and in the appendedclaims.
